Support Zentinel
Zentinel stays open source. You pay for assurance and operational deliverables.
Zentinel exists to keep critical web infrastructure boring, inspectable, and shared. We believe security-focused edge infrastructure should be transparent, forkable, and free from vendor lock-in.
Your support funds CI/CD infrastructure, security audits, documentation, and the maintainers who keep Zentinel production-ready. Whether you're a solo developer or an enterprise team, there's a way to contribute.
Sponsors
Sponsorships support ongoing development and help keep Zentinel free for everyone.
Enterprise Builds
Production-ready artifacts for teams that need supply chain security, compliance documentation, and long-term stability. All releases already include signed binaries, SBOMs, and SLSA provenance for free. Enterprise adds LTS, early advisories, and config stability on top.
Signed Artifacts
Binaries signed with Sigstore/cosign with full provenance attestation. Verify authenticity before deployment.
SBOM & Vulnerability Reports
SPDX and CycloneDX software bill of materials. Automated vulnerability scanning with each release.
LTS Releases
Long-term support branches tied to CalVer series (e.g., 26.01 LTS). 12-month security backport windows. Patch releases stay on the same series — no feature churn.
Config Stability
Guaranteed configuration compatibility within an LTS window. A config that works on 26.01_0 works on 26.01_12.
Security Advisories
Early notification of security issues with patch timelines. Private disclosure before public announcement.
Update Channel
Automated update notifications with checksums. Integrate with your deployment pipeline.
Enterprise Builds
Everything your procurement team needs to approve Zentinel for production.
